Why Choose the ABB TSR Bell Buzzer Transformer Unit?
The ABB TSR is a compact modular bell and buzzer unit with an integrated transformer, designed for acoustic signalling in residential, commercial and public-sector electrical installations. As part of the ABB modular command and signalling range, it combines audible signalling and the required low-voltage transformer within a single DIN-rail device.
Designed for discontinuous operation, the TSR is typically activated through one or more pushbuttons and is suitable for applications such as door signalling, call systems and general acoustic notification. Its integrated transformer operates from a 230 V AC primary supply, eliminating the need for a separate external transformer for the signalling unit.
The TSR incorporates both bell and buzzer acoustic signalling, with approximately 80 dB at 1 m for the bell and 70 dB at 1 m for the buzzer. Its compact two-module construction measures 35 mm wide and is designed for convenient installation within modular electrical distribution boards.
Key Advantages
- Integrated bell, buzzer and transformer in one modular unit.

Integrated Acoustic Signalling for Electrical Installations
The ABB TSR combines a transformer with two forms of acoustic signalling in one modular device. Its bell and buzzer functions provide distinctive audible indications, making the unit suitable for door signalling, call systems and other applications where an easily recognisable acoustic alert is required.
Designed for intermittent activation through one or more pushbuttons, the TSR is particularly suited to residential, commercial and public-building installations. The integrated transformer reduces the need for separate components, while its two-module DIN-rail construction allows convenient integration into modular electrical distribution equipment.
Typical Applications
- Doorbell and entrance signalling systems.
- Residential acoustic signalling.
- Commercial building call systems.
- Public and tertiary-sector buildings.
- Pushbutton-operated audible notification systems.
- Electrical distribution boards.
- General discontinuous acoustic signalling applications.

Frequently Asked Questions
What is the ABB TSR used for?
The ABB TSR is a bell and buzzer unit with an integrated transformer designed for discontinuous acoustic signalling in residential, commercial and public-building electrical installations.
What supply voltage does the ABB TSR require?
The TSR operates from a 230 V AC primary supply and incorporates the transformer required for its low-voltage signalling circuit.
Does the ABB TSR include both a bell and a buzzer?
Yes. The TSR incorporates both bell and buzzer functions, providing approximately 80 dB at 1 m from the bell and 70 dB at 1 m from the buzzer.
Does the ABB TSR have an integrated transformer?
Yes. The transformer is integrated into the TSR unit, allowing the device to operate from a 230 V AC primary supply without requiring a separate external transformer for its acoustic signalling functions.
Is the ABB TSR designed for continuous operation?
No. The TSR is specified for discontinuous operation and is typically activated through one or more pushbuttons for intermittent acoustic signalling.
